Next Full Moon is the Harvest Moon of September 2023 after 21 days on 29 September 2023 at 09:57.

Upcoming main Moon phases

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 292 of Meeus index or 1245 from Brown series.

Synodic month length 29.67 days

Length of current 292 lunation is 29 days, 16 hours and 2 minutes. It is 13 minutes shorter than next lunation 293 length.

Lunation length longer than mean

Length of current synodic month is 3 hours and 18 minutes longer than the mean length of synodic month, but it is still 3 hours and 45 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠179.2°

This lunation true anomaly is ∠179.2°. At the beginning of next synodic month true anomaly will be ∠202.9°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).

Moon before apogee

7 days after point of perigee on 30 August 2023 at 15:51 in ♒ Aquarius. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 5 days, until it get to the point of next apogee on 12 September 2023 at 15:42 in ♌ Leo.

Distance to Moon 392 278 km

Moon is 392 278 km (243 750 mi) away from Earth on this date. Moon moves farther next 5 days until apogee, when Earth-Moon distance will reach 406 289 km (252 456 mi).

Moon after ascending node

4 days after its ascending node on 3 September 2023 at 07:44 in ♈ Aries, the Moon is following the northern part of its orbit for the next 10 days, until it will cross the ecliptic from North to South in descending node on 17 September 2023 at 19:18 in ♎ Libra.

Moon before northern standstill

11 days after previous South standstill on 26 August 2023 at 20:22 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.095°. Next day the lunar orbit moves northward to face North declination of ∠28.168° in the next northern standstill on 8 September 2023 at 13:18 in ♊ Gemini.

Syzygy in 7 days

After 7 days on 15 September 2023 at 01:40 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
